Welcome to the Katadyn Vario Camping Filter System 8014931 Video Page. TheKatadyn Variowater filter combines the benefits of a ceramic filter with those of a pleated filter by allowing you to choose whichever filtering mode is best for the water you’re treating. When filtering dirty or silty water, the ceramic filter can be engaged, slowing the flow rate of the filter, but lengthening the effective life of the primary pleated filter. The Vario contains three distinct filtering elements: 1) Ceramic disc1.0 micron prefilter that can be adjusted, 2)Pleated high performance 0.3 micron glass fiber filter, and 3)Replaceable activated carbonfor eliminating odors. The Vario is the perfect choice for campers, hikers, adventurists, and survivalists. Great for any outdoor application where pure, safe water is needed. The Vario is small, lightweight, portable and, like a fire extinguisher, everyone should have one on a shelf for emergency situations.
